The public federal record on N604KA, read the way a buyer, lender or insurer reads it: FAA registration, prior tail numbers keyed on the serial number, reuse of the tail number, recent registry filings, and the NTSB accident record under this and every earlier registration.
Registration status is "N-number assigned, not registered, pending cancellation". An aircraft cannot be operated on an invalid or expired registration; resolve this with the FAA before any transaction. [1]
No airworthiness certificate is on file. Usual for a newly registered aircraft, a project, or an aircraft that has not flown since a change of registration; ask for the certificate. [1]
No earlier tail number is recorded against serial 2157854050427 for this model in the deregistered file. [2]
N604KA was previously assigned to 1 other aircraft: Amstutz Curtis J BD-5B (serial 1, cancelled January 9, 2018). Histories keyed to the tail number alone can mix aircraft up; this check keys on the serial number. [2]
No bills of sale, loans or releases have reached the registry in recent weeks. The index covers only recent filings; older liens are in the records file. [3]
1 NTSB record under N604KA: Accident on May 26, 2017 at Portland, IN: no injuries, substantial damage. Details below. [4]
These live in the FAA aircraft records file (every document ever filed against the aircraft) and, for larger aircraft, the International Registry. Part of the full report.
AD compliance against the logbooks and flight-activity reconciliation are researched layers of the full report.
